KA78XXE/KA78XXAE
3-Terminal 1A Positive Voltage Regulator
May 2006
Features
■ Output Current up to 1A
■ Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24V
■ Thermal Overload Protection
■ Short Circuit Protection
■ Output Transistor Safe Operating Area Protection
Description
The KA78XXE/KA78XXAE series of three-terminal posi-
tive regulator are available in the TO-220/D-PAK package
and with several fixed output voltages, making them use-
ful in a wide range of applications. Each type employs
internal current limiting, thermal shut down and safe
operating area protection, making it essentially inde-
structible. If adequate heat sinking is provided, they can
deliver over 1A output current. Although designed pri-
marily as fixed voltage regulators, these devices can be
used with external components to obtain adjustable volt-
ages and currents.

Notes:
3. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must
be taken into account separately. Pulse testing with low duty is used.
